SKYLIGHT CONSTRUCTION.

Application filed April 14, 1916.

To all whom it may concern:

Be it known that l, VVALLAOE G. LYON,

and to the letters and figures of reference marked thereon, which form a part of this specification. I

This invention relates to new and useful improvements in construction of skylights and the object in view is to produce a novel cushioning means, consisting of a helix or coil of flexible metal as a bedding or support for glass panels, so that parts of the coil may yield to conform to any irregularities there might be in the under surface of the glass panels of the skylight.

Another and an important feature of the invention is in the provision of means for sealing the glass panels upon their outer faces by the provision of sealing members connected with the astragal caps, which serve to clamp and hold the sealing members against the outer face of the panels and cans ing the knife edges of the sealing members to conform to and produce line contact with the surfaces thereof.

The invention comprises various otherdetails of construction, combinations and arrangements of parts which Wlll be hereinafter fully described, shown in the accompanying drawings, and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure l is a small scale top plan view ofv a section of a skylight made in accordance with my invention. Fig. 2 is a sectional view on line RR of Fig. 1, showing a section at the ridge. Fig. 3 is a large scale top plan view, a portion being broken away to illustrate the metallic coils forming bearings for the glass. Fig; i is a sectional view on line C0 of Fig. 1, showing a section through a cross gutter. Fig. 5 is a sectional view on line of Fig. 1, showing a section through the eaves gutter. Fig. 6 is a sectional view through an astragal on line AA of Fig. 1. Fig. 7 is an enlarged de- Specification of Letters Patent.

tail sectional view through a portion of an astragal cap and sealing member and illustrating a portion of a panel of glass against which the sealing member contacts, and Fig. 8 is a sectional view of sealing member F having a vertical knife-edged wall in line contact with the glass panel.

Reference now being had to the details of the drawings, it will be noted upon reference to Fig. 6 of the drawings, showing a cross sectional view through an astragal of a skylight construction, a sheet A, made of any suitable material, is bent as shown to form trough-shaped flanges B and C. A longitudinal central portion of the sheet is bent as shown in Fig, 6 and is apertured for the reception of the T-head threaded bolts D which are arranged at intervals along the ridge and astragal caps. Said sheet A is held to the upright portion of the core bars B by means of the rivets G, said core bars being fastened by rivets G to the clips G which in turn engage the purlins G E designate astragal caps which are apertured for the reception of the bolts D, and D designate nuts fittedupon the bolts D and are adapted to bear against the horizontally disposed portion of the caps E. The opposite edges of the astragal caps E are bent as at D shown clearly in Figs. 6 and 7 of the drawings, and F designate sealing members, which are of the usual construction of canoes of standard manufacture and made of yielding metal, such as lead, the lower edges of which are sharp and adapted to rest upon and conform to any unevenness in the upper surface of the panels of glass, designated by letter F, when the nuts D, shown in the drawings, aretightened upon the bolts, causing pressure to be applied to the sealing members through the caps and thereby make a tight or sealed 1' oint intermediate the sealing members and the upper surface of the glass.

Helices or coils of wire of lead, lead alloy or other suitable yielding metal, designated by letter T, rest in the trough flanges B and form a yielding bedding or support for the panels of glass, whichrest theron, the top of the coils being suiiiciently high above the edge of the trough-shaped flanges to permit of the deflection of the glass panels without the same coming in contact with the edges of the said flanges the degree of yielding qualities of the coils being determined by the proximity of the convolutions thereof to one another, it being understood that the nearer the convolutions are to one another the greater w1ll be the sustaining strength of the helix to resist compression and diminishing correspondingly the yield ing of the same under pressure which might come upon the coils, or by varying the de-' gree of hardness of the lead alloy, if used in lieu of pure lead, or by both. Said coils form means whereby when the nuts D are tightened upon the bolts, the panels of glass are pressed down upon the coils'of sealed oint underneath the panel, the purpose of the present invention beingfto seal the water from the outer or upper surface of the panel instead of upon the under surface thereof which has heretofore been a common practice in skylight construction. I

Referring to Fig. 4 of the drawings will be seen across gutter designated by letter K, which is bent to form two gutters, designated respectively by letters K and L, while a portion of the sheet is bent upon itself at N and thence at right angles, having a portion 0 forming a support for the glass 7 nut R The panels of glass T, shown 1n Fig. 2 of the drawings, rest upon the lead panel Q, which part 0 rests upon a lead coil Q, while the edge of an adjacent panel of glass. Q rests upon the angled edge L and also rests upon the coil. In said Figs. 4.

and 6 of the drawings, it will be noted that.

any water which might run through the space intervening between the lower end of the glass panel Q, and the portion of the gutter K which is bent upon itself, and which might rise up the inclined surface of the portion 0 would be caught in the gutter K and any moisture which might back up underneath the bent portion N, which 6X- tends over the ,uppersurface of the glass panel Q would be caught in. the gutter L and conveyed therefrom lIltOl the gutter (3,

shown in Fig. 6 of the drawings.

In Fig. 4. of: the drawings, the astragal ,cap L is held means. of the T-bolts D the upper surfaces of the glass panels Q and r with the nuts D thereon in the same manner 7 as shown in Fig. 6, formingmeans'whereby the cap Ltinay hold the cames L against Q forming a tight joint intermediatethe same and which in turn will cause the panels to press upon the wire. coils, making the latter conform to the irregularities in the 'under surface of the panels while the sharp edges of thecames conform to any irregularities upon theupper surface of the glass panels forming sealed joints.

In F'g. 5 of the draw ngs, two gutters,

fdesignated respectively by letters J and J,

are formedas shown withthe sheet J bent upon itself,'forming a troughJ which supports the lead coil J 3 uponwhich the glass- J rests, the edge of the sheet forming the gutter J 2 being bent over the upper end of ing J while the gutter J has a similar opening J and through which any water which.

might accumulate in the gutter; J 6 may'run into the gutter J and thence outthrough the exit opening J The inneredges of the two sheets J and J rest upon the skylight curb support 'J and which also. supports the bracket J InFig. 2 of the drawings is illustrated a sectional view through the ridge of the skylight and in which the ridge cap is designated by letter M, which is bent in a similar manner as shown in Fig. .6 with its opposite edges bentas illustrated and each resting upon a sealing member M. R is a ridge gutter for the support of the glass panels bent to form two gutters R, while the central portion is apertured for the reception of aT-bolt R which passes through an aperture in the cap M and is engaged by a coils T which are adapted, when the nuts R are tightened, to cause the lowersharp edges of the sealing members M, underbythe provision of a skylight construction made in accordance with my invention, I provide means whereby the panels of glass are sealed upon their upper. or outer faces by reason of the sealing members being held under pressure with their sharp edges against the upper facesiofthe glass panels and parts of the edges of the sealing members conform ng to, any irregularit es there might be in the surface of. the glass. .In the 7 event of water from; any I cause running down through the spaces intermediate the upper ends of the glass panels and the ridge gutter upon which the latter rests, it will be caught by the gutters R and It and con-.

veyed JaWay thereby to main gutters C,

shown clearly in Fig. 6.- Itwill also be 'notedithat, by the provision of the coils of lead or other suitablematerial,asupport or V bedding is afforded for the panels of glass uponthe coils which will, under pressure,

conform to any irregularities. upon the I under surface of the glass. i j What I'claim to. be new is:.-

s l 1.. Ina roofconstruction, and in combina 1 30' tion with a panel thereof, a cushioning member for supporting said panel, said member consisting of a helix formed of a strip or wire composed of a yielding material, upon the upper surface of the convolutions of which the lower face of said panel rests.

2. In a skylight construction and in combination with panels thereof, cushioning members for supporting said panels, each of said members consisting of a helix formed of a strip or wire composed of yielding material, upon the upper surfaces of the convolutions of which the lower face of said panels rest, and water tight sealing members, making a line contact with the upper surface of said panels and being water tightly connected to covering caps or crown pieces of the skylight astragal.

3. In a skylight, an astragal having trouglrshaped outstanding wings or flanges,

cushioning members removably and replaceably supported upon the trough of said wings or flanges, each cushioning member consisting of a helix formed of a strip or wire composed of a yielding material, and glass panels having their under surfaces resting upon the top surface of the convolutions of said helix.

4. The combination with an astragal cap having a laterally flanged edge of a sealing strip having a channel in its top surface adapted to receive said flanged edge and one or both walls of the channel being folded down behind said flange.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
